94 PUECHASE OF CAMELS FOR MILITARY PURPOSES. 



RIBS. 



The ribs of the dromedary are twelve in number, like those of 

 the ox. 



KIDNEYS. 



The two kidneys, composed, if it may be expressed thus, of a mul- 

 titude of little kidneys, are more bulky than those of the horse ; how- 

 ever, they do not offer the same conformation as those of that animal 

 and the ox; they resemble a large, round, enclosed ear-ring. They 

 are composed of three different substances. Each kidney weighs one 

 and a half pounds; one is generally larger than the other. 



HEART. 



The heart of the dromedary resembles that of the horse ; the auri- 

 cles are twice as large as those of the heart of the latter. 



LIVER. 



The liver is composed of a large number of lobules, of a lozenge 

 shape, which can be lifted up separately and which are more promi- 

 nent on one side than on the other. The substance of it is firmer and 

 more granular than that of other animals. The liver of the drome- 

 dary is divided into two, as that of the horse, whilst that of the ox is 

 composed of one piece alone. 



DOUBTS RESPECTING THE EXISTENCE OF THE BILIARY FLUID. 



All the researches made in order to find the yellowish fluid which is 

 called bile in the viscus of the abdomen, called the liver, which is 

 composed of different glands fitted to separate that liquid from the 

 mass of the blood, (Lavoisier's Dictionary of Medicine,) have been 

 fruitless. It is generally known that the gall bladder, which always 

 exists in the carnivorous animals, is wanting sometimes, even often, 

 in the herbivorous; so it is not astonishing to find that bladder absent 

 in the dromedary. But what is surprising is, that in the case of the 

 animals who have died even after a long abstinence, no trace of bile 

 is presented in the ducts of the liver. 



OF THE GENITAL PARTS OF THE DROMEDARY. 



The formation of the genital organs of the male dromedary is in all 

 respects similar to that of those of the bull, excepting that the sheath, 

 being directed backwards, draws with it the end of the yard, which 

 changes in direction for the act of coupling. 



The vagina of the female is the same as that of the cow ; the urinary 

 duct into the vagina is, however, more narrow in the first. The papa 

 are placed between the thighs, as in all the ruminants. 



CALLOSITIES. 



The callosity of the sternum, the asseous portion of the front of the 

 chest, is formed of a soft horn, or tumour without hair, in all respects
